About the Product:
Advances in automobile design have resulted in improved “sound proofing” of the passenger compartment of modern vehicles. The average decibel rating for emergency vehicle sirens in the United States is approximately 120 decibels at 10 feet. As distance from the siren increases, the decibel level decreases. There have been no comparable improvements in siren technology.

When you factor in other distracters vying for a driver’s attention such as cellular telephones, portable music players, global positioning satellite (GPS) devices, or even conversation among passengers; it is easy to understand how a motorist may be unaware of the presence of emergency vehicles and/or road hazards. Additionally, hearing impaired drivers rely solely on the visible emergency lights from an emergency vehicle as a warning.

If more than one emergency vehicle is responding to an incident or separate incidents, a driver may not hear a second or third siren. Also, the emergency vehicle operator is unable to hear the sirens of other responding emergency vehicles.

The result of these factors is evident: an increased danger level for both civilians and emergency vehicle operators when driving with emergency light bars activated.

The Multiple Emergency Vehicle Alert System (MEVAS) is an innovative system that greatly enhances a driver’s awareness as an early warning system or proximity warning system. Each equipped emergency vehicle emits a pulse radio signal with an identifying code anytime its emergency lights are activated. Vehicles equipped with MEVAS will receive this signal as they approach or are approached by the emergency vehicle(s) even if the emergency vehicle(s) were sent by different dispatchers and are responding to different incidents. The driver is notified by an audio and visual alert of the number and type of each emergency vehicle(s). This allows the driver advanced warning to take the appropriate action (i.e. slow down, pull to the right shoulder, look for changes in traffic patterns, etc.).

It is anticipated that when MEVAS receivers go into mass production, their cost would be less than $50.00 per unit.
